keypad can also transmit a low battery
alert to the receiver.
Range
Communications Security
Spread spectrum technology is designed
to operate in an indoor area 300 x 300 feet
(90 x 90 meters). A room’s geometry and RF
propagation characteristics will influence
the actual range experienced.
A proprietary response verification protocol
integral to the radio design provides a high
degree of signal security.
Speed
Default speed is 200 keypads per second.
Polling rates are adjustable and can achieve
½-second speed in groups of 100 or less.
Power and Power Management
Powered by one replaceable lithium cell
battery.
• Energy-intelligent keypad powers down
after each response to conserve battery
life.
• Battery life is ~20,000 responses or 12
month of shelf life, whichever comes
first.
• Low battery indicated on display. The
Frequency hopping and proprietary data
communications are additional deterrents
to clandestine interception.
Scalability
500 keypads per receiver channel and 31
channels available for 15,500 keypads per
room/site.
